Here's a story (perhaps apocryphal) from a friend of mine who worked at Subway for years. Just before the whole Jared ad campaign came out, Subway was looking for ways to market themselves as a healthier fast food alternative. They didn't have any light or low-fat mayo yet, just regular, so they wanted to try to find a low-fat mayo to over as an option. Well, their mayo was already pretty low fat (as far as standard mayo's go) and they couldn't find a low fat version that tested well. So, the solution: rename the normal mayo they sold as Light Mayo and introduce a higher-fat version of their mayo as the plain old normal mayo. Like I said, I don't know if that story is true, but if you look up the nutrition fact for light mayo and compare it to Subway, it seems to pan out.
